The 4500C series electric strike is designed for installation in 2" UL 10C fire-rated frames with ½" drywall penetration. The 4500C features a low profile 1-3/8" depth, heavy-duty stainless steel construction. Its strength is derived from a unique keeper pin locking design, enabling the 4500C to exceed the ratings of the frame, door and locking hardware. The 4500C comes with two faceplates designed to accommodate either cylindrical or mortise locksets up to a 3/4" throw latchbolt.
